While Mew is a popular Pokémon, it's not a playable character in the Mystery Dungeon series. The playable Pokémon are usually from the starter Pokémon pool, and Mew is not included in that pool for any of the games.
Here's why:
* Story Purpose: Mew is a very powerful Pokémon, and allowing it to be playable would make the game too easy. The developers wanted to create a balanced experience where players face challenges and strategize to overcome them.
* Gameplay Mechanics: The Mystery Dungeon games are based on a specific set of rules and mechanics that are built around the playable Pokémon pool. Adding Mew would require significant changes to the game's balance and structure.
* Rarity and Uniqueness: Mew is a very rare and special Pokémon, and keeping it as a non-playable character adds to its mystique and sense of wonder.
While you can't play as Mew directly, you can still encounter it in the game! It appears as a rare event, and there are other ways to incorporate Mew into your gameplay experience.
Here are some options:
* Trading: Some versions of the game allow you to trade Pokémon with other players, so you might be able to obtain a Mew through trading.
* Fan-made mods: Some fans create mods that add new features to the game, including playable characters. These mods are usually available online and may offer the ability to play as Mew. However, be cautious when downloading and using mods as they may not be compatible with all versions of the game or may cause instability.
Remember, playing as Mew is not possible in the official versions of the Mystery Dungeon games. But there are ways to encounter and interact with Mew in the game, and perhaps even indirectly experience playing as it through fan-made mods.
